5. Key Features
5.1 The Serif Design
The Serif is a collaboration between Samsung and the Bouroullec design duo, blurring the lines between technology and furniture. Its distinctive 'I' shaped profile allows it to stand out as a design piece, whether on its easel stand or placed on a surface. When off, it doesn't just display a black screen; it can transform into a decorative element.

The Serif TV seamlessly integrates into various home decors, acting as both a television and a design statement.
5.2 100% Color Volume with Quantum Dot
Experience vibrant and true-to-life colors with Quantum Dot technology. This feature allows the TV to produce over a billion shades of color, maintaining accuracy even in bright scenes, providing an immersive viewing experience.

Near Field Communication (NFC) allows for effortless content mirroring. Simply tap your compatible Android mobile device to The Serif to instantly mirror sound, making it easy to share music from your phone directly to the TV's speakers.
5.4 The Serif Ambient Mode+
Beyond being a television, Ambient Mode+ allows The Serif to become an integral part of your living space. Instead of a blank screen, it can display decorative patterns, artwork from the Bouroullec palette, personal photos, or useful information like time and weather, blending into its surroundings.
